A URL that catches webhooks, and tells you why they fail.

hooks.bot gives you a disposable endpoint that records every request sent to it, and a debugger that works out why a webhook signature will not verify — rebuilding the signature every way it could plausibly have been made and naming the step that differs. No account, no API key.

Your coding agent can drive all of it over MCP at https://hooks.bot/mcp — create an endpoint, wait for the webhook to land, and diagnose it without anything being copied by hand. Tools: create_endpoint, wait_for_request, list_requests, get_request, diagnose_signature.
